Castle of San Antón

Castelo de San Antón

A 16th-century seaside fortress that guarded the harbor, now an archaeology and history museum with Celtic gold jewelry and city history exhibits.

San Antón Castle was built in the 16th century. It originally stood as a fortress on a small island at the harbor entrance, was later used as a prison, and is now connected to the mainland by a causeway. Inside is an archaeology and history museum with Celtic-era gold torcs from Galicia, Roman artifacts, and exhibits about the English siege of 1589. From the walls you can look out over the harbor and the glass gallery across the bay. Admission is about €2, and the castle is closed on Mondays. Walking along the harbor from María Pita Square takes about 15 minutes, and it can be combined with the Old Town and San Carlos Gardens on one route.
